Removal

Based on the settings of your F-Secure security product, it will either move the file to the quarantine where it cannot spread or cause harm, or remove it.

A False Positive is when a file is incorrectly detected as harmful, usually because its code or behavior resembles known harmful programs. A False Positive will usually be fixed in a subsequent database update without any action needed on your part. If you wish, you may also:

  • Check for the latest database updates

    First check if your F-Secure security program is using the latest updates, then try scanning the file again.

  • Submit a sample

    After checking, if you still believe the file is incorrectly detected, you can submit a sample of it for re-analysis.

    Note: If the file was moved to quarantine, you need to collect the file from quarantine before you can submit it.

  • Exclude a file from further scanning

    If you are certain that the file is safe and want to continue using it, you can exclude it from further scanning by the F-Secure security product.

    Note: You need administrative rights to change the settings.

Technical Details

Variant:Rut.A

When an infected document is opened, W97M/Rut.A infects the global template. After that every document that is saved is infected.

During infection, the virus might cause Visual Basic compile errors. Anyway, the virus will still be able to replicate.

The virus activates its payload in every 10th, 18th and 27th day of the month. At this time it displays a dialog with the following text: 

Created by F?D
 DVD version 1.0
 (C)opyright 1997

This dialog contains two buttons as well. If user selects the "OK" button, no further action is taken. However, if "About" button is selected, the virus asks user to enter a text string which is either 

I LOVE HD-LWP

or

DJAJA HD-LWP is Good

depending the number of the seconds. If the string is entered correctly, the virus displays yet another message box with the text: 


Terima kasih telah mengetikkan dengan
benar. Saya dedikasikan kreasi saya ini untuk HD- LWP. Semoga HD-LWP selalu dilindungi oleh-Nya.
Jangan takut DVD tidak akan merusak data Anda, apalagi sampai menghapusnya. DVD hanya akan mejeng setiap tanggal-tanggal tertentu saja.
